It is line_2: believed that these PN nuclei have temperatures in excess of 100000dK and the line_3: large flux in the far ultraviolet produces a nebular surface brightness that line_4: overwhelms the stellar radiation in the visual when resolution is seeing line_5: limited. The WF/PC spatial resolution will enhance the contrast by the order line_6: of 100 while an additional enhancement will be achieved by observing in the UV. line_8: This program should result in the detection of these central stars and provide line_9: sufficient photometric data to determine the nature of the central star and line_10: interstellar extinction. ! ! end of abstract general_form_proposers: lname: WESTPHAL fname: JAMES mi: A. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The observations require several exposures with different filters in order to line_2: cover the wide spectral range from 1500 angstroms to 6220 angstroms, required line_3: to determine interstellar extinction and effective temperature. Early line_4: observations in cycle 0 and 1 will provide support for further observations of line_5: these objects with WF/PC or other instruments. ! question: 5 section: 1 line_1: No real time or special scheduling required. ! question: 8 section: 1 line_1: No supporting or coordinated observations required. ! question: 13 section: 1 line_1: This program is planned in order to detect the central stars in NGC 7027, NGC line_2: 2440, Me2-1, and IC 2165 where they have not been detected, presumably because line_3: the bulk of the radiation is in the form of ionizing photons. The photometry line_4: should provide data on the effective temperature of these stars. ! !end of general form text general_form_address: lname: WESTPHAL fname: JAMES mi: A. title: PROF. category: PI inst: CALTECH addr_1: M/S 170-25 addr_2: DIVISION OF GEOLOGICAL & addr_3: PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC7027 descr_1: G, 502, 910 pos_1: RA= 21H07M0.2S +/- 0.1S, pos_2: DEC= +42D14'18" +/- 1" equinox: 2000 pm_or_par: NO comment_1: PLANETARY NEB NUCLEUS ! targnum: 2 name_1: NGC2440 descr_1: G, 502, 910 pos_1: RA= 07H41M54.4S +/- 0.1S, pos_2: DEC= -18D12'34.5" +/- 1" equinox: 2000 pm_or_par: NO comment_1: PLANETARY NEB NUCLEUS ! targnum: 3 name_1: ME2-1 name_2: 342 +27.1 descr_1: G, 502, 910 pos_1: RA= 15H22M18.2S +/- 0.1S, pos_2: DEC= -23D37'40" +/- 1" equinox: 2000 pm_or_par: NO comment_1: PLANETARY NEB NUCLEUS ! targnum: 4 name_1: IC2165 descr_1: G, 502, 910 pos_1: RA= 06H21M42.8S +/- 0.1S, pos_2: DEC= -12D58'44" +/- 1" equinox: 2000 pm_or_par: NO comment_1: PLANETARY NEB NUCLEUS ! targnum: 5 name_1: PSF-NGC2440 descr_1: A, 704 pos_1: RA= 07H 41M 31.04S +/- 0.1S, pos_2: DEC= -17D 49' 32.1" +/- 1" equinox: 1950 pm_or_par: NO comment_1: PSF STAR FOR NGC2440 ! ! end of fixed targets !
